UCC27511: UCC27511

Part Number: UCC27511
Other Parts Discussed in Thread: UCC27611, LMG5200, LMG5200POLEVM-10

Hi,

UCC27511 is a low side MOSFET driver, I would like to know if there is any evaluation kit using this part so that I can test it to see if the performance satisfy my requirement.

Thanks in advance.

    Yanqi,

    On the product folder for UCC27511, under the "Tools & Software" tab, there are 2 EVM's listed that might be suitable.

    The UCC27611 EVM is a general-purpose driver eval board, but uses the UCC27611 driver. This is similar to UCC27511 in functionality and performance, but has a different package/pinout. It is not suitable for testing the UCC27511, but you may find eval of the UCC27611 to be useful.

    The second EVM is the LMG5200 EVM, which uses the UCC27511 to drive the output SR's. This EVM may be useful to you to evaluate the UCC27511 performance.


    I will ask my colleagues in the drivers team to comment on the differences between the UCC27511 and UCC27611, and on the availability of a dedicated or more suitable EVM for UCC27511.


    If you list your specs and key requirements, they can also comment on the suitability of UCC27511 for your application, and possible recommend an alternative if they feel that another device in the portfolio may be more suitable.


    Thanks,
    Bernard

    Yanqui,

    Currently, TI does not offer a dedicated EVM for the UCC27511 driver. Either of the two options that Bernard mentioned are good tools to evaluate this device. The LMG5200POLEVM-10 will showcase the device in an application. Note that the UCC27611 was designed for driving enhancement mode GaN power FETs, and thus has the ouput drive voltage regulated at 5V.

    One other option to evaluate the UCC27511 is to use a standard breakout board for its quite common SOT-23 package. You can get such boards as part of the DIP-ADAPTER-EVM from TI. Although the layout will not be optimized for capacitor placement and proximity to the load FET, this could be a low-cost, quick way to take a first look at this driver.

    Hi, Daniel and Bernard,
    Thanks for the reply. I am using these devices to drive GaN switches. Since both can be used for GaN switches, I can choose either one of them for testing.
    Thanks for your help.
